1959 -1984, 6 pieces by the legendary Gordon Mumma, much heard of but not much heard (unfotunately). These are pieces made for dance, but work excellently alone. Mumma was one of the non-aligned sonic investigators (like Tudor, he was someone who liked to roll up his sleeves and solder, wiring experimental circuits and then running them). The pieces here range from roaring planes and smoke through spacious zen garden episodes and from bowed psaltery and bandoneon through to collected and synthesised sounds. A wide and panoramic collection that explores sound intelligently and closely that should be in any comprehensive collection.
